           Plan and your 1999 Employee Long-Term Incentive Plan

Dear Sir or Madam:

         Reference is made to the above-captioned Registration Statement on Form
S-8 (the "Registration Statement") filed by Skyworks Solutions, Inc. (the
"Company") on or about the date hereof with the Securities and Exchange
Commission under the Securities Act of 1933, as amended, relating to an
aggregate of 14,011,500 shares of Common Stock, par value $0.25 per share, of
the Company issuable pursuant to the Plans (the "Shares").

         We have examined, are familiar with, and have relied as to factual
matters solely upon, copies of the Plans, the Company's Restated Certificate of
Incorporation, as amended, the Company's Second Amended and Restated By-Laws, as
amended, the minute books and stock records of the Company, and originals or
certified copies of such other certificates, documents, records and materials as
we have deemed necessary for the purpose of rendering this opinion.

         We are members only of the Bar of the Commonwealth of Massachusetts and
are not experts in, and express no opinion regarding, the laws of any
jurisdiction other than the Commonwealth of Massachusetts and the United States
of America, and the General Corporation Law of the State of Delaware.

         Based upon the foregoing, we are of the opinion that the Shares have
been duly authorized and, when issued and paid for in accordance with the terms
of the Plans, will be validly issued, fully paid and nonassessable.

         We hereby consent to the filing of this opinion as Exhibit 5 to the
Registration Statement.


                                            Very truly yours,


                                            /s/ TESTA, HURWITZ & THIBEAULT, LLP
